> Key: FLINK-4679
> URL: https://issues.apache.org/jira/browse/FLINK-4679
> Project: Flink
> Issue Type: Sub-task
> Components: Table API & SQL
> Affects Versions: 1.2.0
> Reporter: Fabian Hueske
> Assignee: Jark Wu
>
> Add TumbleRow row-windows for streaming tables as described in
> [FLIP-11|https://cwiki.apache.org/confluence/display/FLINK/FLIP-11%3A+Table+API+Stream+Aggregations].
>
> TumbleRow row windows are a syntactic shortcut for a special type of SQL OVER
> windows, i.e., windows of the from
> {code}
> SELECT STREAM rowtime,
> productId,
> units,
> SUM(units) OVER (PARTITION BY FLOOR(rowtime() TO HOUR)) AS
> unitsSinceTopOfHour
> FROM Orders;
> {code}
> i.e., OVER windows which are partitioned by the time attribute.
> This issue is about extending the Table API with the TumbleRow shortcut. It
> should reuse the OVER window translation and runtime code implemented by
> FLINK-5653, FLINK-5654, FLINK-5655, FLINK-5656, FLINK-5657, and FLINK-5658.
